BELL.

' Application filed May 15,

This invention relates to electric bells and its primary object is to provide an electric bell wherein the ringing mechanism therefor is confined within the walls of the bell and base thereof respectively.

A further object is to provide an electric bell-which is very simple in construction, composed of few parts and which may be manufactured cost.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

' In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a front elevation of the bell which forms the subject matter of the present invention; I

Figure 2 is a side elevation thereof showing the same in applied position.

Figure 3 is a rear. view.

Figure 4- is a sectional view taken on line -lat of Figure 1.

Figure 5 is a sectional View takenon line 5-5 of Figure 3.

Figure 6 is a sectional View taken on line 6,6 of Figure 3.

Figure 7 is a view'of a stamped blank from which the armature of the bell is formed. r I

Figure 8 is a sectional view taken on the line 88 of Figure 3. I

Referring to the drawings in detail the reference numeral 1 indicates the base for. the bell 2 and extending from the flange 3 and secured upon diametrically opposite sides thereof is a substantially usshaped bell receiving bracket 4 having formed in its outer portion a threaded opening 5 to accommodate the screw bolt 6 which also passes through an opening formed in the bell for securing the same to the bracket in the manner as illustrated in Figure t'of the drawings. The bracket adjacent its outer portion is provided with a pair of spaced parallel ears 7 which are aperturedto receive rounded projections formed upon opposite and assembled at very little 1926. Serial N0. 109,352.

sides and'adjacent one end'of the armature arm 8 which is formed from the blank as shown in Figure .7 and bent substantially at right angles to its ends as indicates at 9 V and 10. The end 10 has secured thereon-the hammer 11- for the bell and the end 9 has fixed thereto a weight 12 for a purpose which will be apparent.

The contact breaker arm is indicated by the reference numeral 18 and has one end insulated from and secured to the flange 3 of the base through the instrumentality of a terminal nut and bolt connection 14, while the opposite end is bent downwardly upon itself and receives the thumb screw 15 which ture 8 so. that the core thereof will attract the armature for causing the operation thereof and which has formed integral therewith and cut therefrom as illustrated in Figure 7 thestrip 19 .which is arranged to engage the contact maker and breaker strip 16 for causing the same to cooperate with the screw bolt 15 to provide the intermittent operation of the armature with the result that the hammer thereof will strike the bell accordingly. 7

The electrom'agnet is supported by a link 19 which provides the ground connection therefor and which is secured to the flange 'Elby the terminal 20 as clearly shown in Figure 3 of the drawings. The terminals 14 and 20 are provided with the usual binding nuts for attaching the positive and negative conduitsfroin a suitable source of electric energy not shown.

The base 1 has detachably associated therewith a plate 21 which is formed with a key hole shaped slot 22 so that the bell can be adequately supported from a nail or similar means 23 in the manner as best illustrated in Figure 4. V

It is thought fromthe foregoing descriptionthat the advantages and novel features of my invention will be readily apparent.

Idesire it to be understood that I may make changes inthe construction and in the C(Illlljllltllltill and arrangement of the several parts, provided that sueh changes fall with in the FCOPO oi the appended claim.

lvhat I claim isi An electric hell of the character described comprising a base, a substantially U-shaped bracket; secured thereto and rising therejt'rom, ears extending laterally from the ln'aehet, an armature arm, rounded projections extending from the arm and being mounted for pivotal movement in the ears, a eontast breaker arm having one end seeuredto and insulated from said base, a strip having one end eeeured to and insulate FY0111 sun! muse, a thumb nut threadedly F0- rured in the contact breaker arm and adjustably arranged in the path of the strip, an eleetromagnet iwitionettl 90 that it may attract the armature arm and beingeleetrieally (:onnoctedgvith the etrip, a strip cut from and integrally formed trith the arma- :ERHARD MARTIN 'ITl-lADlCN.
